Product Description

Viperdet MS Dual is a non-electric detonator assembly with a high strength in-hole detonator on one end and a low shrapnel surface detonator in a colour coded connector on the other.

A colour coded label marked with the specified delay is attached to the shock tube within 10cm of the connector.

Viperdet MS Dual


Viperdet MS Dual is used for initiation of explosives in open-pit mines, underground non-coal and non-methane mines, quarries and construction works. Viperdet MS Dual detonators may be used in underground mines, where there is no coal dust and/or methane explosion hazard. The connector can hold up to 6 shock tubes and is designed to ensure easy connection, and reliable initiation while minimizing shrapnel damage to the shock tube.
